A straight wire of length 0.5 m carries a current of 10 A perpendicular to a magnetic field of 0.1 T. What is the force on the wire?

Answer and explanation

Correct answer: A. 0.5 N

  1. Step 1: for a conductor perpendicular to the field.
  2. Step 2: N.
Answer
0.5 N.
Why not the others: 2 N: length is divided. 50 N: the field strength is in the denominator. 10.6 N: the values are added.
